摘　　要：以层析硅胶为载体负载3种不同杂多酸制备高活性吸附脱氮剂,以润滑油基础油为原料油,在全混流反应釜中进行静态吸附实验。考察吸附温度、吸附时间、剂油质量比、杂多酸负载量对吸附剂吸附性能的影响,并进行动力学模型的拟合和计算。结果表明,在吸附温度为60℃、吸附时间为30 min、剂油质量比为1∶5、酸负载量为40%时,润滑油基础油可以达到较好的吸附脱氮效果,脱氮率达到90%以上。利用FT-IR和BET分析测定了吸附剂的骨架结构及吸附剂的比表面积和孔分布情况,结果表明硅胶已成功固载杂多酸。A high active nitrogen-removing agent is prepared by using chromatography silica gel to load three different heteropoly acids.Taking lube base oil as raw material, static adsorption experiments over the agent is performed in a full mixed reaction kettle.Impact of adsorption temperature, adsorption time, the mass ratio of agent to oil and the loading amount of heteropoly acids on the adsorption properties is studied, and the dynamic mode is fitted and calculated.Study result shows that the best nitrogen-removing effect for lube base oil can be achieved with a removal rate more than 90% when adsorption temperature is at 60℃,adsorption time is 30 min, the mass ratio of agent to oil is 1∶5,and the loading amount of the agent is 40%.The skeleton structure, specific surface area and pore distribution of the agent are characterized by FT-IR and BET.It is proven the silica gel has successfully supported heteropoly acids.
